Couplings
Derwent Couplings® were recently added back into the Derwent range with a new state of the art robotics manufacturing facility being established in North East Victoria.
The Stainless Steel Couplings (Kawandah®TM ) were developed for the Australian and export markets by the Evans Group of companies, in Wangaratta Victoria. The iconic logo of the Cockatoo (Current trademark) is the logo we are still proud to use today to represent the range.
Derwent Industries Kawandah Variable Couplings are Australian manufactured. The couplings have been designed to alleviate the issues encountered when connecting pipes of different outside diameters and/or pipe materials. The coupling provides the installer with a precise simple way of connecting pipes that have OD variances of up to 24mm.
Derwent Industries manufacture and distribute under the Derwent brand the range of mechanical Couplings. Derwent also has an additional sourced range of Gripper and Stepped Couplings to service industry requirements.
